Security Rules Overview

Security Rules Overview

A security rule defines the criteria that the Rule Engine uses to parse and rewrite an SQL request. A security rule is part of a security rule set. You can create a security rule in a rule folder or as a rule in a rule tree.
Security rules specify the technique that the Rule Engine uses to mask data. Security rules consist of a matcher, a rule action, and a processing action. Security rules mask data in a row or column. For example, create a security rule that rewrites SQL requests that reference the Social Security column from the Employee table.
Connection rules define the security rules that the Rule Engine applies. Use the connection properties to define security rules for Microsoft SQL Server.
Dynamic Data Masking supports request packets in UTF-8 format. If the machine on which you install Dynamic Data Masking has a different default encoding method, you can change the method by updating the
jvm.params
file. Dynamic Data Masking might not work as expected for requests sent in non UTF-8 format.
